Hi

Im using the htz270

I remember during buying the salesman show me the capability to select HDMI IN but using some trickery button combination in the remote control.
After few month i bought can't seem to recall how to do it.
1)Any one got idea how to do it? what to press on the remote? as it is not stated in the manual.
2)And any idea whats the function for HDMI IN? Can we use for let say PS3 audio out in this case?
